Support for AMS lite vertical stand

Author not allowed to post remix file, so i add it seperately, because its addition for original projekt.https://makerworld.com/en/models/796462-ams-lite-rotating-stand-for-a1?from=search#profileId-735644 It reduce wobbling, makes stand more stabilized. And looks great, in my opinion. All you need to assemble is 3 m4*50 screws and nuts.
